4.6 PROGRAM OPTIONS AND EDITING

4.6.1 SEQUENCE NUMBER (SL)

There are 5 programmable screw fastening sequences (SL = 'U1' to 'U5') available. In many cases, only the
first sequence (U1) will be needed. If the screwdriver is used to install a batch of fasteners with varying
requirements, multiple sequences may be necessary. For example, if an assembly requires the installation
of 4 screws, where 3 screws are short, and 1 screw is long, the controller can be programmed with 2
unique sequences - a sequence for the short screws and one for the long screws. This would allow different
time windows to be set-up for the two difference screw lengths. Each sequence must be programmed
separately, and numbered in the order that the screws will be installed (starting with sequence U1). In this
example, if the 3 short screws are to be installed first, enter the program for sequence 'U1' with a batch
quantity of 3 and time parameters for the short screw. Then repeat the program steps for sequence 'U2'
with a batch quantity of 1 and the time parameters for the long screw. Finally, program sequence 'U3' with
a batch quantity of '00' to signify that there are no further fasteners to install.
(For multiple sequences, refer also to info on setting dip switch #6 later on in this manual)

4.6.2 BATCH COUNT SETTING (SC)

Enter the desired number of fasteners to be installed per batch. Depending on the setting of DIP switch #1,
the display will either count down from the total batch value entered, or count up to the total batch value.
The count will only increment (and indicate 'GOOD' rundown) if the rundown cycle falls within the limits set
by the min and max rundown time settings (see below). When all fasteners in the batch have been installed,
the controller will indicate that the batch complete and the count will reset for the next cycle. If, after a good
rundown, the operator runs the screwdriver in reverse, the batch count value will decrement by a count of
one (based on the assumption that the operator is removing the last installed fastener). The batch count
can be reset to begin a new batch by pressing ON/CLEAR key.

4.6.3 END OF BATCH RESET TIME (RT)

When a rundown batch is completed, the controller provides a visual indication (count = '00') and audible
indication (depending on audible settings) that the batch is complete, followed by a reset of the display
count for the beginning of the next batch. The END OF BATCH RESET TIME value determines how long
these indicators will stay on before the batch count resets. Please note that the screwdriver cannot be
operated during this reset time period.
4.6.4 SLOW START TIME (RC) and SLOW START SPEED
(SP)
Please refer to the section entitled 'Screwdriver Speed Adjustments' for further information on the Slow
Start function.
